Description

Technical Field [0001] The present invention relates to a non-woven fabric structure for a cosmetic pack,

The present invention relates to a nonwoven fabric structure for a cosmetic pack and a method of manufacturing the same. More particularly, the present invention relates to a nonwoven fabric structure for applying a hydrogel component excellent in moisture retention and functionality to a cosmetic pack, and a method for producing the same.

Generally, a cosmetic mask pack is prepared by immersing a cosmetic composition in a nonwoven fabric. However, in the formulations in which the serum is simply immersed in the nonwoven fabric, there is a disadvantage in that the serum can be flowed down during use, resulting in poor user convenience and poor skin adhesion and poor nutrient delivery to the skin.

Recently, inventions using a hydrogel as a beauty pack mask have been proposed. According to the present invention, the hydrogeling composition is immersed in a single layer of a natural or synthetic nonwoven fabric to form a mask pack to form a mask pack or a hydrogel single layer.

In Korean Patent No. 10-0841742, a composition prepared by mixing fibroin aqueous solution and one substance selected from the group consisting of alginate, cellulose and agar is poured into a frame having a predetermined shape, and then the frame is immersed in an aqueous metal salt solution, alcohol or distilled water A manufactured hydrogel mask pack is disclosed. However, in the case of such a hydrogel mask pack, since there is no supporting structure and the mask pack is formed of a single layer of hydrogel, it is difficult to maintain its shape and its tensile strength is weak, so that hydrogel residue remains on the skin or uniform removal There is a drawback that it can be difficult.

Korean Unexamined Patent Application Publication No. 2010-0003456 discloses a method in which a non-woven fabric is adhered on a hydrogel in order to compensate for the disadvantages of a mask pack formed of a nonwoven fabric and a mask pack formed of a hydrogel, and after applying the essence to the nonwoven fabric, And an essence gel mask pack using a paper, a hydrogel and an essence as a pack. However, also in this case, the hydrogel layer is exposed to the outside air and the essence component contained in the hydrogel layer evaporates, resulting in insufficient moisture sensitivity for a long period of use, and the mask pack function is lost, which is not suitable for a high-function mask pack structure.

Korean Patent No. 10-1692376 discloses a nonwoven fabric comprising a first release sheet, a nonwoven fabric having a first surface coated with the first release sheet and a second surface coated with a cosmetic composition, and a second release sheet bonded to the other surface coated with the cosmetic material of the non- Wherein the cosmetic material does not flow out of the first release paper and the second release paper. However, in this case, since the release paper is used only for maintenance of the cosmetics during storage and distribution, and is removed when the mask pack is used, it has the same problems as the Korean Patent Publication No. 2010-0003456.

Hereinafter, the present invention will be described in detail with reference to the embodiments of the present invention. However, the present invention is not limited to the following embodiments. , And may be implemented in a variety of different forms. The singular forms herein may include plural forms unless the context clearly dictates otherwise. Also, to the extent that the term "comprises" or "comprising" as used herein is intended to specify the presence of stated features, integers, steps, operations, elements, elements and / And does not preclude the presence or addition of elements, operations, elements, elements, and / or groups.

1 is a cross-sectional view illustrating a nonwoven fabric structure according to an embodiment of the present invention.

As shown in FIG. 1, the hydrogel layer 200 containing a cosmetic ingredient is shown sandwiching and fixed between the first nonwoven fabric layer 110 and the second nonwoven fabric layer 120.

In practice, the first nonwoven fabric layer 110 is in contact with the skin surface to supply the serum to the skin. Therefore, it is preferable that it is composed of a hydrophilic cellulose long fiber which is hypo-environmentally friendly material. In order to supply the active ingredient and water contained in the hydrogel layer to the skin well, a nonwoven fabric exhibiting hydrophilicity should be used. On the other hand, when the mask pack is removed, it becomes a protective film between the hydrogel layer and the skin film, thereby helping to remove the mask pack cleanly without remaining hydrogel remaining mass.

Cellulose is a major constituent of the cell wall of plants. It is abundant in nature, has no toxicity, can be regenerated, has three hydroxyl groups, is highly hydrophilic, has biodegradation and modification properties, and has potential to be used in various fields It is known as a natural polymer. A cotton linter can be used as a raw material of the cellulose used for the mask pack, and it is not only natural but also non-toxic, and has a high purity of? -Cellulose content of more than 95%, which is very suitable for cosmetic pack applications. The cellulose linter-based cellulose filament nonwoven fabric is excellent in adhesion to the skin because of its flatness, flatness, and lint-free property, unlike a short fiber nonwoven fabric, has excellent wettability due to its high absorption and swelling property, Is preferable.

It is preferable that the weight per unit area of the first nonwoven fabric layer has a weight per unit area of 1 to 40 g / m ² . When the weight per unit area is higher than the above range, the structure becomes excessively dense and a sufficient average pore diameter can not be ensured. As a result, the function of transferring the cosmetic ingredient and moisture is deteriorated. Conversely, The function of fixing the hydrogel layer due to the decrease in mechanical strength can not be properly performed.

The second nonwoven fabric layer is a nonwoven fabric layer positioned on the side exposed to the outside air, and its function is to prevent evaporation of the support component structurally supporting the mask pack as a whole and the cosmetic component to the outside. Since the second nonwoven fabric layer is not in direct contact with the skin, a nonwoven material to which raw materials such as synthetic fibers are applied for economical reasons can be applied. For example, polyethylene terephthalate, polybutylene terephthalate, A nonwoven fabric material composed of at least one material selected from the group consisting of terephthalate, polyamide, ethylene vinyl copolymer, polylactic acid, and polybutylene succinate can be applied.

The weight per unit area of the second nonwoven fabric is preferably 30 to 150 g / m ² . The weight per unit area of the nonwoven fabric is appropriately adjusted in consideration of the tensile strength, the cosmetic ingredient and the degree of moisture evaporation associated with the role as a structural support of the hydrogel layer.

The surface of the first nonwoven fabric layer 110 and the second nonwoven fabric layer 120 that are in contact with the hydrogel layer 200 may be further subjected to a hydrophilic treatment to further improve the fixing force of the hydrogel layer 200. In this case, the hydrophilization treatment can be performed by a known method such as dipping, spraying, coating or the like, using a diluted hydrophilic solution. Also, prior to the hydrophilization treatment, surface treatment such as corona treatment, And the like.

It is preferable that the average pore diameter present in the second nonwoven fabric layer 120 is smaller than the average pore diameter present in the first nonwoven fabric layer 110 in order to prevent evaporation of the serum component.

The mean pore diameter of the nonwoven fabric is measured by ASTM F 316 (bubble point method). In the case of the first nonwoven fabric layer, the average pore diameter is preferably 20 to 90 m, and in the case of the second nonwoven fabric layer 1 To 40 m. When the average pore diameter satisfies the above range, it is possible to realize proper intertwining of the fibers, and it is possible to satisfy the softness of touch, the stretchability of the sheet, and the ability to transmit a cosmetic ingredient and moisture.

The hydrogel according to the present invention can be obtained by firstly mixing the alginic acid, alginate, gellan gum, locust bean gum (LBG), xanthan gum, carrageenan, sodium citrate, Calcium lactate, cellulose, and agar may be used. A hydrogel refers to a state in which a large amount of water is swollen and filled in a lattice of a polymer material to maintain a three-dimensional structure.

As a cosmetic ingredient used in the present invention, a whitening agent, a moisturizing agent, a wrinkle improving agent component and the like may be added. As the whitening agent, substances such as arbutin, lucinol and vitamin C can be used. As the moisturizing agent, substances such as squalene, glycerin, glucose, hyaluronic acid and the like can be used. As the wrinkle improving agent, collagen, mushroom extract, pineapple and coconut extract, But the present invention is not limited thereto.

Hereinafter, a method of manufacturing a non-woven fabric for a cosmetic pack according to an embodiment of the present invention will be described with reference to FIG.

Referring to FIG. 2, first, an alginate, an alginate, a gellan gum, a locust bean gum (LBG), a xanthan gum, carrageenan, sodium citrate, calcium lactate at least one substance selected from the group consisting of calcium lactate, cellulose and agar is mixed with water at a concentration of 0.1 to 10% to prepare a hydrogel composition (S100). At this time, the cosmetic active ingredients described above can be added as needed.

The hydrogel composition thus prepared is poured into a mold to form a gel (S200). At this time, the gelation process of the hydrogel composition may be performed by immersing the frame in an aqueous metal salt solution, alcohol, or distilled water.

When the hydrogel composition is a component such as alginate or xanthan gum, it is preferable to immerse the mold in an aqueous metal salt solution. When the composition contains cellulose, it is preferable to immerse the frame in alcohol. When the composition includes agar, the composition is preferably immersed in distilled water. The metal salt may be a salt of a Group 2 or Group 3 metal of the Periodic Table of the Elements such as calcium, magnesium, barium or aluminum, preferably a calcium salt.

In the method of manufacturing a hydrogel mask pack according to another embodiment of the present invention, it is also possible to extract the gel by centrifuging the hydrogel composition thus prepared, and then to pour the gel into a mold to form a hydrogel layer.

Next, the first nonwoven fabric layer and the second nonwoven fabric layer are laminated on both sides of the hydrogel layer (S300), and the hydrogel layer is fixed to the first and second nonwoven fabric layers through instantaneous heating (S400) The nonwoven fabric structure for a cosmetic pack according to an embodiment of the present invention is completed.

The step of laminating the first nonwoven fabric layer and the second nonwoven fabric layer followed by the instant heating is performed at a temperature of 50 to 190 ° C for less than 10 seconds. When heated at a high temperature for a long time, the hydrogel layer may be deformed and the fixing force may be lowered.
